The threat of a shutdown is proving somewhat cathartic for conservative Republicans, many of whom were elected in 2010, promising to do everything they can to kill off Obama’s health care law.

Republicans feel comfortable with the possible political repercussions of shutting down the government. They believe that their effort to delay or defund Obamacare is vital for the economy and personal freedom, and worth risking their House seats over.

“I might be the wrong person to ask on this, because I’m pretty unique in this,” said Rep. Tom Graves (R-Ga.), who led the push to defund the law as part of a short-term government-funding bill. “I’m not concerned about personal impact, I’m more concerned about personal real impact of my constituents and this law. I made a commitment in August I would do everything I could to protect them from it.”…

“Listen, our biggest struggle is to get the economy back on track,” Farenthold insisted. “We’ve tried spending cuts. We’ve tried the president’s tax increases… I think the consensus — certainly within my conference — is that Obamacare is the biggest thing in the way of economic growth.”
